Human Multidrug Transporter P-Glycoprotein (PGP) is a membrane protein capable of exporting a variety of molecules out of cells. In some cancers, it contributes to drug resistance by removing drug molecules from the tumor cells.
This schematic graphic summarizes the findings of a cryo-electron microscopy (cryo-EM) paper featuring 10 different structures of the human multidrug transporter P-glycoprotein (PGP), and places them in context of PGP’s ATPase cycle.
